How to Install an Electrical Box in Framing

Take this important electrical step before putting up your drywall. You'll thank yourself later!

Wiring is easier before the walls and ceilings become covered with drywall or plaster. Installing electrical boxes while studs and joists are exposed is a handy and simple solution for homeowners.

To do this on your own, buy switch and receptacle boxes that meet local codes and are large enough for the wires they hold. It's easy to underestimate, so buy extra supplies. At the same time you install boxes, attach fans, lights, or other fixtures that need to be hardwired.

Local codes specify where cable should run and at what height to place receptacles and switch boxes. Check codes before you begin.

Step 3 Attach to Stud or Joist

Drive the box's nails into the stud or joist. If the box attaches with a flange, drive screws or nails to anchor the box.

Editor's Tip

If desired, use a mud ring to attach the box. Adapter rings, also called mud rings, are typically 1/2 inch or 5/8 inch thick. Choose a ring that matches the thickness of the drywall or paneling you install. Attach the box flush with the front edge of the framing member, then add the ring.
